Observability is the ability to monitor and measure the state of a system, including its performance, health, and behavior. It is an important part of software development in the JavaScript domain, as it allows developers to detect problems with their code and be able to quickly identify and fix them. Observability also allows for debugging and analyzing applications, and helps developers understand how their code is behaving in real-time.

Watch video: Observability Matters: This Time for Frontend
Hi, everyone! My name is Yash Varma, and I'm a software engineer and computer researcher. I'm an open telemetry enthusiast, working on creating a vendor-neutral observability framework. Today's talk is titled as Observability Matters, this time for frontend. We'll cover the evolution of ZEP, the understanding of observability, current state of front-end monitoring tools, core essence of front-end observability, and front-end observability direction. Observability is about understanding what's happening inside the system based on its internal behavior or output. Front-end developers often lack observability compared to back end developers. Synthetic monitoring and real user monitoring are two common tools used by frontend developers. Front-end observability allows us to understand application performance for different users and situations, connecting the dots and gaining insight into core web vitals and user sessions. It's time to adopt observability as a culture and break down silos between front-end and back-end to better understand the entire user experience.

Observability for React Developers
In this talk, observability in React web applications is discussed, covering Rome agents, open telemetry, and synthetic monitoring. The importance of logs, metrics, and traces in tracking application behavior and identifying issues is explained. The concept of a real user monitoring agent (rum agent) for JavaScript applications is introduced. Instrumenting the rum agent and React applications is explained, along with the caution to be mindful of the bundle size. Traces, open telemetry, and instrumentation are explored, including how Core Web Vitals, traces, and open telemetry can provide insights and enable auto-instrumentation. Synthetic monitoring using Playwright tests and the process of converting tests into monitors with configuration is covered. Finally, running and monitoring definitions in production is discussed, highlighting the ability to evaluate user behavior, simulate activities, and address issues proactively.

Observability with diagnostics_channel and AsyncLocalStorage
Observability with Diagnostics Channel and async local storage allows for high-performance event tracking and propagation of values through calls, callbacks, and promise continuations. Tracing involves five events and separate channels for each event, capturing errors and return values. The span object in async local storage stores data about the current execution and is reported to the tracer when the end is triggered.

Getting Started with Open Source Observability
Observability is a crucial tool for engineers to ship reliable websites and have a good developer experience. Metrics, logs, and traces are fundamental data types for achieving observability. OpenTelemetry is an open source standard for observability data, and instrumentation can be done manually or automatically. Data collection and transportation can be handled by packages built by the OpenTelemetry community, and the collector running can add security benefits. Grafana is used for data visualization, and it allows for analyzing web performance, exceptions, and traces. Traces capture user interactions and provide insights into user behavior and error occurrences. Leveraging these tools allows for gaining insights into various parts of the system and improving engineering goals.

Observability for Microfrontends
Microfrontends follow the microservices paradigm and observability is crucial for debugging runtime production issues. Error boundaries and tracking errors help identify and resolve issues. Automation of alerts improves incident response. Observability can help minimize the time it takes to understand and resolve production issues. Catching errors from the client and implementing boundaries can be done with tools like OpenTelemetry.
